Re: Instant OID's

Situation is that I'm using Nagios but I dont know really understand OID's or SNMP so much.


I can get info like:

check_command               check_snmp!-C password -o .

I get system uptime

check_command               check_snmp!-C password -o .
I get ArubaOS version


But when I try

check_command               check_snmp!-C password -o


I get error iso. = No Such Object available on this agent at this OID

Any help?


Thanks. J

Re: Instant OID's

Here is the solution, you need to use SNMP WALK to get AP info of your IAP cluster to work, and for that you need a perl script.

To get this to work you need to have a basic knowledge about configuring Nagios.

So what I did is I ripped a script called check_cisco_ap.sh found from http://exchange.nagios.org/directory/Plugins/Hardware/Network-Gear/Cisco/Check-Cisco-AP-Number/details


(Thanks to Marco Gottardello for the script)


And did few changes to the script


usage="Usage: check_cisco_ap -H <hostname> -C <community> -N


usage="Usage: check_aruba_ap -H <hostname> -C <community> -N




num_of_ap=`/usr/bin/snmpwalk -v 2c -c $community $hostname | wc -l`


num_of_ap=`/usr/bin/snmpwalk -v 2c -c $community $hostname iso. | wc -l`


Save the file and rename it to "check_aruba_ap.pl"

Upload to the server where you have Nagios installed to the folder called libexec (my path is /usr/local/nagios/libexec)


Edit your command.cfg file and add a line



# 'check_aruba_ap' command definition
  define command{
  command_name    check_aruba_ap.pl
  command_line    $USER1$/check_aruba_ap -H $HOSTADDRESS$ $ARG1$       


add a line to services.cfg


define service {
    hostgroup_name        Instant Virtual Cluster AP amount 2pcs
    service_description        SNMP Virtual Cluster AP amount 2pcs
    check_command               check_aruba_ap! -C password -N 2
    use                    generic-service
    notification_interval    0 ; set > 0 if you want to be renotified


And do as many as you need, in this case we are expecting to have 2 AP's on a cluster. Just replace the -N 2 to some other number (-N exoect) -C is the community string.

Then create a file called for example "my_aruba.cfg"

And add the basic Nagios stuff into it:


############ ARUBA ##############

define  host {

use                                            generic-host
host_name                               My Company Controller
alias                                         My Company Controller

check_command                      check-host-alive
hostgroups                                   Instant Virtual Cluster AP amount 2pcs
notifications_enabled           1       ; Host notifications are enabled
event_handler_enabled           1       ; Host event handler is enabled
flap_detection_enabled          1       ; Flap detection is enabled
failure_prediction_enabled      1       ; Failure prediction is enabled
process_perf_data               1       ; Process performance data
retain_status_information       1       ; Retain status information across program restarts
retain_nonstatus_information    1       ; Retain non-status information across program restarts
max_check_attempts              10
notification_interval           1
notification_period             24x7
notification_options            d,u,r,f,s
contact_groups                  admins

And also edit hostgroup.cfg and add


define hostgroup {
    hostgroup_name        Instant Virtual Cluster AP amount 2pcs
    alias                            Instant Virtual Cluster AP amount 2pcs


Restart Nagios (service nagios restart) And you're done!
